UNITED STATES PATENT OFFICE JOHN NORTH, OF MIDDLETOWN, CONNECTICU l,ASSIGNOR TO HIMSELE, AND D. APPLETON & CO., OE NEV YORK, N. Y.

REGISTER FOR SHEETS 0F PAPER.

Specification of Letters Patent No. 23,221, dated March 8, 1859'.

To all whom 'it may concern:

Be it known that I, Jol-1N NORTH, of Middletown, in the county ofMiddlesex and State of Connecticut, have invented a certain new anduseful improved mode of making register point-holes in sheets of paperwhile on the feedstable in the process of printing for the purpose offeeding in register to a folding-machine and also a cer tain new anduseful mode of effecting this object by attaching suitable mechanism tothe feedtable, frame, and carriage of the ordinary printing-press; and Ido hereby declare that the following is a full and exact descriptionthereof, reference being had to the accompanying drawings and to theletters of reference marked thereon.

Figure l, is a perspective view of a printing press with the carriage D,to which the trip lever moving the apparatus referred to attached, theplaten O, and the feed table B, which is perforated with the registerholes required for the working of the apparatus, the apparatus itselfbeing attached under the feed table. Fig. 2, represents the feed tableturned upside down, showing also inverted the apparatus for making theregister points. Fig. 3, is a section of the earriage D, showing thetrip lever R, and the cam X, which last is attached to frame Fig. l.

My invention consists in attaching to the feed table two additionalregister points, and operating them for the purpose of making registerpoint holes in the half sheet of paper in the process of printing.

To make the required register point holes in the half sheet, I attachtwo additional register points made adjustable at y, y, and made tooperate at the proper time by the advance of the carriage D. The sheetbeing placed on the feed table on the points, c, c, as usual in printingpresses, upon the advance of the carriage D, to take the sheet to beprinted, the trip lever R, attached to the carriage at H, is raised bymeans of the cam X, Fig. 3. This cam is attached to the frame. The triplever R, being raised, as it goes on raises the lever P, which is attached to the shaft m, hung in the boxes o, 0, and thereby at the sametime raises the lever n, attached to shaft m, which operates the twolevers 2, 2, which are hung in the studs J, J. lVhen the carriage movesto take the sheet from the feed table, the trip lever It, is raised bythe cam X, the lever R, coming in connection with lever P, the latter israised, and when the carriage is at the proper place to receive thesheet, the trip lever It, drops, and thereupon by the force of thespring S, the lever 1t, strikes the levers 2, 2, and forces the twopoints z', i, up through the sheet and makes register for the foldingmachine.

The mode heretofore used of making register in sheets is to place thepoints on the frisket which lies over the type form. The sheet on beingtaken from the feed table lies on the frisket over the points, and iscarried under the platen C, where the sheet receives its impression andpoint holes at the same time. This method of making register point holesis very objectionable, as it injures the rubber cloth which is fastenedto the platen O, the points forcing the small particles of paper intothe rubber cloth and making it uneven. The rubber cloth is soon spoiledby this means, and has to be taken off and renewed at great expense andtrouble. To obviate this difficulty and make the points more easilyadjustable to suit different sized sheets and pages, is the object of myinvention.

Having thus fully described my lnode and apparatus for making registerpoint holes, what I claim as my invention and desire to secure byLetters Patent is,

l. The attaching to the feed table of the printing press of two or moreregister points in addition to those commonly used for printing, so asto make register point holes in-the sheet to be printed at the exactpoints required for the purpose of feeding the sheet in register tofolding machines to be folded.

2. I claim the application for that purpose of the above describedmechanism or other suitable mechanism of the same general description,yattached to the feed table, frame and carriage of the printing press,and which will produce the intended effect.

JOHN NORTH.
